摘要
Abstract
A new process was developed for synthesis of acrylated alkyd resin in which a methyl methacrylate (MMA) is copolymerized with a maleinized alkyd resin.The effect of the concentration of MMA and initiator
addition methods on the film properties has been investigated.It was showed
compared with the conventional modified alkyd resin
the MMA modified alkyd resin made by the new process is superior in appearance of film
impact resistance and resistance to petrol.The new process broadens the materials source of modified alkyds
reduces the cost of product.The satisfactory formulations are obtained with 30%-40% of methyl methacrylate
3.0% of initiator and 60%-70% maleinized alkyd resin.The key technique in this process is the addition method
which MMA and based alkyd are added into reactor together
and initiator is introduced into the reacted mixture gradually in four hours.
